Engine Rattle

[setshot50]

My GP has developed what sounds like a high frequency metal rattle at low RMPs. When I lightly press on the gas petal I hear the sound, but when I get above about 30mph the sound lessens and/or disappears. I have heard claims of a heat shield but was curious if others had experienced this problem. Many thanks.

Check the heat shields bolted to the exhaust manifolds.. Mine were loose from factory, like they started the bolt by hand and forgot to torque them down, one bolt was ready to fall out

Thanks for the reply. I will make certain to give those a once over.
